I was driving home today check engine popped up went to get it checked I was told bank one sensor one code p0130 are these easy to change or do you think maybe something is loose and what do I need to change them and how to do you do it.I have a 1996 se 123,000 miles someone please help because if I can change it and save me some money I will.

 

Yes the O2's are easy to chaneg, and just so you know you need to replae all of them at the same time to get the best beinifit, if one is bad then the others are to follow...soon.
But first things first, when was the last time you had a tune up? In need of a tune up will set off O2 codes.

 

Well I changed them out myself I bought two of them for 236.00 dollars a a place called bap geon the were ngk brand made in japan when I took off the old ones they were the same brand and man what a differance it made wow!!!!

 

So what about the other 2? Too bad you jumped the gun, Atlantic British has them on sale for $99 a piece.
Replace your other two so you get the full benefit of 4 new 02's.
